Product Title
Martyr – Zinc Teardrop Hull Anode 5-1/4 x 2 in – CMT-T21

Product Description
The Martyr CMT-T21 is a zinc teardrop hull anode designed for hull and underwater metal corrosion protection in saltwater service. Martyr’s commercial teardrop anode range includes this compact size for hull applications where a smaller streamlined anode body is needed.

Key Features

• Zinc sacrificial teardrop hull anode
• Martyr part number: CMT-T21
• Designed for saltwater use
• Compact teardrop profile for hull protection
• Nominal size: 5-1/4 in. x 2 in.

Application / Compatibility
Suitable for hull and underwater metal protection where a 5-1/4 in. x 2 in. zinc teardrop anode is required. This is a size-and-style-based fitment item rather than an engine-specific part, so matching by overall dimensions, body style, and mounting configuration is the safest method.

Fitment Notice
Fitment should be confirmed by anode size, mounting style, and installation location before ordering. Matching by CMT-T21 and the existing anode dimensions is the safest approach.

When This Part Needs Replacement
Replace the anode when it is heavily wasted, pitted, cracked, loose, or significantly reduced in size. Hull anodes should be inspected regularly because they are designed to sacrifice themselves first in order to protect the hull and nearby underwater metal components.

Installation Notes
Install using the correct mounting method for the specific hull application and do not paint the anode body. Confirm the existing anode style and dimensions before service so the replacement matches the original setup.

Alternate / Superseded Part Numbers when applicable
No confirmed superseded number was found in the reviewed sources for CMT-T21.

Parts Desk Insight
The main thing to match on hull anodes is size and mounting style, not just shape. A teardrop anode like CMT-T21 is chosen to give sacrificial protection with a compact streamlined profile, so getting the dimensions right matters.
